To all whom it may concerm.

` Be it known that I, Is'AAo Gr. WATERMAN, ao

citizen of the United States, residing at Santa Barbara, in the countyof Santa Barbaraand Stateof California,` have invented new and usefulImprovementsin Electric Switches, of which the following is aspecification.

This invention relates to electric switches.y

In my application filed MajT 11, 1903, Serial No. 156,671, I have shownan electrical system with certain electromagnetic valves, automaticcut-olf lioat, and switches for controlling the fiow f water to and frombath-tubs and lavatories. In the operation of that system three switchesare used, one being for the control of the hot water, another to controlthe cold Water, and a third to control the H eretofore I haveconstructedthese switches as independent switches, those controlling the hot andthe cold water being combined in one switch, and thewaste-valvecontrolling switch being separately made. In the presentinvention I propose to combine in one switch the switches for operatingthe hot and -cold water valves and the switch for controlling thewaste-valve, thereby obtaining a more -compact and cheap-system ofswitches and saving time and labor in installing the switch mechanism.

Another object is to provide an improved electromagnetic mechanism forthrowing the switches used for controlling the hot and cold water.

A further object is to provide an improved oscillatory switch forcontrolling the waste lvalve.

Having the foregoing objects in view, the

invention consists of certain improved features and novel combinationsof parts set forth in detail hereinafter and recited inthe appendedclaims.

In'the accompanying drawings, Figure 1 is a vertical section showing themechanism in elevation; Fig.'2, -a bottom plan view with the lower partof theshell removed. Fig. 3

' is an end elevation; Figs. 4 and '5, detail views of theelectromagnetic-switch-throwing mechanism; Fig. 6, a detail view of thewaste-- 17 and two rounded notches 18 and 19.

valve-operating switch; Fig. 7 a detail of one of the ratchetvwheels 9.v

The mechanisms and electromagnet are inclosed in an iron shell 1,'thehorizontal part of whichis formed in sections to permit easy accesstothe mechanisms.

The numeral 2 designates the face-plate having the back plate 3, towhich the frame 4 is secured.

Extending across the frame 4 is a shaft 5,

on the end portions of which are Vjournaled the duplicate rotaryswitches 6 and 7, intermediate which is the rotaryswitch 8. The rotaryswitches 6 and 7 each consists of a central ratchet-wheel 9,contact-tumblers 10 and 11 on opposite sides thereof and separatedtherefrom by insulation 12, and a two-pointed ratchet-wheel 13. l Thetumblers 10 and 11 each have contact projections 14 and 15disposeddiametrically and set "quartering to the contact projections onthe other tumbler. The intermediate oscillatory switch 8 has a disk 16,provided with a single tooth or lug Disposed alongside the disk 16 andconnected thereto is a contact-tumbler 20, having thediametrically-disposed contact projections 2l and 22. f

On the frame 4 is an insulating-block 23, to which is secured pairs ofupper and lower contact-fingers 24 and 25, positioned to be engaged bythecontact projections 14 and 15, and other contact-fingers, 26 andl 27,are em- -ployed which are adapted to be engaged by the contactprojections 21and 22.

Slidable through face-plate 2 are push-buttons 28, 29, and 30, havingstems 3l slidable through the back platey 3 and encircled by springs 32,which keep the push-buttons nor- Vmallyprojected. Pivoted to the ends ofthe stems of push-buttons 28 and 29 are actuating pawls or dogs 33 and34, held in engagement with vthe ratchet Wheels 9 of the rotary switches6 and 7 by springs 35.

Pivoted to the end of the stem of pusli-but ton-30 are two actuatingpawls or dogs 36 and 37, adapted to engage opposite sides of the lug 17ofthe intermediate oscillatory switch 8, said pawls being pressed by therespective L springs 38 and 39. The teeth of these pawls are eachdisposed a little distance away from the lug 17, in consequence of whichonly one of them, 36, engages the lug 17 when the pushbutton is pressedin, and then on the return movement of the push-button the other pawl,37, engages said lug. Consequently the contact projections 21 and 22remain for an instant against the contact-fingers 26and 27 when thepush-button is pressed in and are then snapped backwardly oil1 of saidlingers to their former position. By this improved switch I obtain asomewhat longer contact than with the other switches or those other"temporary-contact switches set forth in ctlergain applications which Ihave previously e The rotary switches 6 and 7 are held where snapped byspring-pressed rollers 40 and 41 entering the interdental spaces of theratchetwheels 9, and it will be understood that these switches are ofthe snap type and make only a momentary or temporary engagement withtheir contact-lingers. The oscillatory switch 8 is held where snapped bya springpressed roller 42, adapted to enter either the notch 18 or notch19.

The numeral 43 designates a solenoid in which is a stationary slottedguide-rod 44, on which slides the armature 45, which has a pin 46movable in the slot 47 of the rod 44, whereby the armature is preventedfrom turning. The armature has two pawls or dogs 48 and 49 pivoted toits head, which are pressed by springs 50 into engagement with therespective two pointed or toothed ratchet-wheels 13 on the rotaryswitches 6 and 7.

In using the invention with a system such as shown in my copendingapplication filed May 11, 1903, Serial No. 156,671, the rotary switches6 and 7 control the circuits of the hot and cold water electromagneticvalves and the oscillatory switch 8 the circuit of the electromagneticwaste-valve. The purpose of the electromagnet or solenoid and the pawls48 and 49 is to automatically throw the rotary switches 6 and 7 when acurrent is sent through said solenoid. In my system set' forth in theapplication, Serial No. 156, 672, filed May 11, 1903, the current forthe solenoid is controlled by certain automatic electricalcontact-controlling iioat mechanism.

1n the present application I lay no claim to the switch mechanisms 6 and7 and their pushbutton actuating devices per se, as similar switchmechanisms are claimed in substance in other applications which I havefiled heretofore.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with a movable switchcontact and another contactarranged so that on the electromagnet adapted to engage either of theengageable members aforesaid to turn the rotary contact.

3. The combination with a rotary contact,

of an actuating member for manually operating said rotary contact, stepby step, an electrom'agnet, and an armature adapted to rotate the rotarycontact independently of the actuating member aforesaid.

4. The combination with a rotary contact, of an actuating member formanually operating said rotary contact, step by step, an electromagnet,an armature therefor, and a pawl on the armature adapted to rotate therotary contact independently of the actuating member aforesaid.

5. The combination with independentlymovable contacts, of means formanually operating said contacts independently, an electromagnet, anarmature therefor, and independent pawls on the armature adapted toindependently cooperate with the movable contacts to operate them.

6. The combination with a movable contact, of another contact forengagement therewith, and an actuating device for said movable contactadapted to move it back and forth on each actuation, said actuatingdevice having two members, one adapted to engage the movable contact tomove it in one direction on the initial movement of the actuating deviceand the other adapted to engage the movable contactto move it back tonormal .position on the final movement of the actuating device.

7. The combination with a movable contact having a lug or projection, ofanother contact for engagement with the movable contact, and anactuating device having two pawls adapted to alternately engage saidprojection to move the contact back and forth.

8. The combination with a movable contact having a lug or projection,and another contact for engagement with the movable contact, and anactuating device havingtwo pawls positioned to engage opposite sides ofthe lug or projection to move the contact back and forth, said .pawlsbeing each movable back and forth relatively to the projection or lug atthe' points where they are adapted to engage said lug.

9. The combination with a contact adapted to move back and forth on eachactuation, of
